Trex: product lineup and their EPD reality
Spec-driven projects increasingly ask for product‑specific EPDs. Trex is a household name in composite decking, railing, and cladding, yet public EPD coverage is still the wildcard. Here is how their portfolio stacks up against the transparency bar projects use to shortlist brands.


Trex in one glance
Trex is best known for wood–plastic composite decking across three flagship lines: Transcend (including Lineage), Select, and Enhance. They also sell aluminum and composite railing systems (Signature, Transcend, Select), cladding, fascia, lighting, fasteners, and deck drainage. Across colors, profiles, and lengths, their catalog spans dozens to possibly hundreds of SKUs.
Their sustainability story is anchored in recycled feedstock. Trex states its decking uses up to 95% recycled and reclaimed content, and reports sourcing about 377 million pounds of plastic film and roughly 674 million pounds of reclaimed wood in 2024 (Trex Sustainability, 2025).

Are Trex products covered by EPDs today
As of December 5, 2025, we could not locate public, product‑specific EPDs for Trex decking, railing, or cladding on the major operator registries that specifiers commonly check. That does not mean the products lack LCAs internally. It does mean project teams may not find third‑party verified declarations to cite during submittals.
Why that matters: many owners and AEC teams now treat an EPD as the baseline disclosure for carbon accounting. Without one, they must rely on generic values that can carry penalties in their calculations and procurement screens.
What competitors are showing
Two frequent rivals have public EPDs available today.
- TimberTech (The AZEK Company) states that EPDs are available for TimberTech decking and for AZEK and Versatex Trim, with access via SmartEPD (AZEK Full‑Circle Sustainability Report, 2025) (SEC Exhibit, 2025).
- Fiberon lists an Environmental Product Declaration for Composite Decking in its literature library and has a third‑party verified EPD for Wildwood composite cladding via SCS Global Services (Fiberon Literature Library, 2025) (SCS Global, 2023).
For bidding, that transparency makes it easier for specifiers to select named SKUs without extra justification.
Where Trex likely competes most
Expect head‑to‑head comparisons against TimberTech (PVC and composite lines), Fiberon (PE composite lines), Deckorators, and MoistureShield, especially in residential, multifamily, hospitality decks, and light commercial terraces. Natural wood is a swap in some scopes. When the spec calls for an EPD, composite brands that publish one jump to the front of the line.
Portfolio breadth and SKU scale
Trex is not a pure play in a single SKU. The mix covers deck boards, fascia, hidden fasteners, three railing families with multiple infills, lighting, and accessories. Taken together, the SKU count lands in the hundreds when you include colorways and lengths. That breadth is great for upsell paths in channel. It also means EPD planning benefits from a portfolio strategy (group by formulation and plant) rather than one‑off documents.
The commercial risk of “no EPD” in 2025
LEED v4.1 awards credit for using products with compliant EPDs and explicitly recognizes program‑operator verified declarations (USGBC, 2024) (USGBC EPD credit guide). In practice, owners often bake that preference into specs for consistency. If a Trex board is pitted against a roughly equivalent TimberTech or Fiberon SKU with a current EPD, the latter can be easier to approve. That can nudge Trex to compete on price or be sidelined when teams chase material credits.
Notable gaps and fast wins
If we had to pick one likely bestseller to prioritize, Transcend Lineage boards are the obvious candidate. A third‑party verified, product‑specific EPD for that series would remove friction in commercial submittals. Railing kits are the second wave. Many teams want deck‑and‑rail packages with matching disclosures, so publish at least one representative EPD per material family.
A pragmatic playbook: map formulations by plant, pick the prevailing PCR used by peers, and publish where your buyers already look (SmartEPD in the U.S., with EN 15804 compatibility if European projects are on the horizon). Capture energy and water data by reference year and lock a strong sampling plan for recycled inputs. It sounds tedious. With the right partner, the data chore gets handled while your engineers stay on roadmap.
How Trex’s sustainability claims still help
Even without current public EPDs, Trex’s verified recycled content and large‑scale diversion of plastic film and reclaimed wood remain strong talking points in non‑EPD‑mandated work (Trex Sustainability, 2025). Those facts resonate with consumer channels and discretionary commercial buyers. They do not replace a Type III EPD when a spec calls for one, which is the key distinction to keep front of mind.
What manufacturers should learn from Trex’s moment
- Breadth is a strength only if disclosures keep up. Start with top‑volume SKUs, then template across similar recipes.
- Give AEC teams a single download path and clean submittal language. If it takes three clicks to find your EPD, it is already too many.
- Watch renewal dates and PCR shifts so you do not wake up with an expired declaration in peak bid season.
Threading it together
Trex has brand gravity, distribution, and a sustainability story people understand. Where they are light is public EPD coverage that busy specifiers can grab and use. In a market that increasingly treats an EPD like an admission ticket, closing that gap on one or two hero lines could pay back fast. It is the difference between being considered first and being asked to “substitute or explan.”
Frequently Asked Questions
Does Trex publish a public, product‑specific EPD for its deck boards or railing as of December 5, 2025?
We did not find a public, program‑operator EPD for Trex decking or railing on common registries as of that date. Competitors list EPDs for similar products, which can influence project submittals.
Do LEED projects actually prefer products with EPDs or is that a myth?
LEED v4.1 awards MR credit for using qualifying EPD‑backed products, and project teams often codify that in specs (USGBC, 2024).
Which competitors in composite decking currently advertise EPDs?
AZEK’s TimberTech cites EPDs available via SmartEPD (AZEK Full‑Circle Sustainability Report, 2025). Fiberon lists an EPD for composite decking and a verified EPD for Wildwood cladding via SCS Global (Fiberon Library, 2025) (SCS Global, 2023).
What Trex numbers can help in non‑EPD projects?
Trex cites up to 95% recycled content, roughly 377 million pounds of plastic film and 674 million pounds of reclaimed wood sourced in 2024 (Trex Sustainability, 2025). These are credible sustainability messages, just not a substitute for a Type III EPD when required.
If starting EPD work on decking, which SKUs first?
Prioritize the highest‑volume board families (for Trex this likely means Transcend Lineage) and produce one representative EPD per distinct formulation and plant. Add railing next so project teams can specifiy a matched set.
